IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 45,823, dated January 10, 1865.

To all whom it may concern Be it known that I, DANIEL D. Grrr, of Arendtsville, in the county of Adams and State of Pennsylvania, have invented certain new and useful Improvements in Harvesters; and I hereby declare that the following is a full, clear, and exact description of the same,

, heretofore obtained Letters Patent of the United States for an improvement having the same object in view; but I have found that the same result may be effected by a more simple contrivance,or by a contrivance of a more simplified construction and arrangement operating in substantially the same manner, but less liable to get out of and more easily kept in working order.

To enable others to make and use my invention, Ishall now proceed to describe my invention in detail and themanner in which the same may be carried into effect.

S in the accompanying drawing is the sickle or cutting-blade, which may be of any ordinary or suitable construction. It receives its reciprocating motion in line parallel with the finger-bar F from a crank moved by a suitable gear mechanism actuated by the driving-wheel of the machine, not shown in the drawing, but which is perfectly understood, it having thatfeature in common with almost every reaping or mowing machine in existence. The movement is thus transmitted through the intermediary of a connecting-rod or pitman, 0, whose outer end is forked to embrace the inner end of the sickle. The connection is effected by means of a. pin, 1), running through corresponding eyes in the forked end of the connecting-rod and the end of the sickle-bar. Upon this pin is mounted a friction-wheel, WV, occupying a central po sition in relation to both the sickle and the connecting-rod, the former, to this effect, be-

ing slotted to admit of the free play of the wheel. I prefer to give this wheel as large a diameter as consistent with the space within which it is to be confined, in order to diminish friction as much as possible. This involves the necessity of curving the forked end .of the sickle-bar upward, so that the cuttingblade may travel in a line parallel and in contact with the finger-bar.

It will be understood that the forked end of the sickle bar may embrace the forked end of the connecting-rod, the main object being the central position in relation to both the friction-wheel and roller. In connection. with, this arrangement I employ a box, B, which incloses the anti-friction connection or the pitman with the sickle. This box may be of a quadrangular form, closed on top and 011 the front side, and is of a length equal to the stroke or extent of reciprocating travel of the said connection, for the purpose of protecting the parts from becoming entangled with the grass, or choked or clogged therewith. The interior sides of this box constitute the ways whereby the inner end of the sickle is guided,

and the top and bottom are the guides against 7 which the roller travels. The height of the box but slightly exceeds the diameter of the wheel, so that rolling contact shall be on but one side at any portion of the stroke. Vhen the connecting-rod is thrust forward, the wheel will roll along the bottom of the box and re volve in the direction of the arrows c. 011 its return the wheel will roll along the top of the box, and of course revolve in the same direction. From this it will be seen that although the sickle has a reciprocating travel, the roller or wheel will have a rotary motion continuously in the same direction.

The box may be made with the front part Having now described my invention, I shall state my claims as follows:

1. Mounting the frictionroller upon the pin which unites the connecting-rod with the Y manner described. 4

sickle, when the said roller occupies a central I11 testimony whereof I have signedmy name position in relation to both, as shown and'deto this specification beforetwo subscribing witscribed. nesses.

2. In combination with the above, the einployment of a box closed on top for the double purpose of guiding and protecting the antifriction connecting device, substantially in the DANL. D. GITT.
